Transfer Weight-Correction Machine for Connecting-Rods 112 TBMP, 212 TBMP - Schenck Japan

  • Modular design for all connecting-rod designs
  • Fully automatic operating sequence
  • Integrated, fast in-line transport
  • Linking with a production line
  • High accuracy through digital measured value processing and numerically-controlled correction procedure

Design

Transfer machine with automatic operating sequence. Modular machine construction, thus optimally adaptable to the task. Arrangement of the stations in an in-line direction with all stations covered by an electro-mechanical lift and carry transfer for transport of the connecting rods. Welded machine base with lateral bases supporting the milling units, prepared for removal of the chips by a chip-conveyor or underfloor extractor. Electromechanical, numerically controlled milling unit and digital operating tandem weighers. Microprocessor-controlled measuring equipment for acquisition of the measured values and processing; machine PLC control with fault diagnosis.
Design

Range of application

Measurement of the weight of rotating and oscillating parts or the absolute weight of machined connecting-rods for internal combustion engines. Controlled weight correction at the prepared correction pads on the small-end and big-end. Weight correction is usually followed by fineboring.
Application of the machine in largevolume production, interfaced with the production line.
